6. R2E - Local PS for fixed pumping groups
R2E motivation: remove sensitive components from local PS crates for fixed pumping groups close to the IT (1st) and then LSS (2nd).
Removal of 2 bipolar transistors (regulated PS => un-regulated PS)
In parallel, adding of new functionalities:
Primary pump passive current measurement
Remote reset of the thermal relay of the primary pump
Pressure switch (5 mbar between VPP and VVI)
These new functionalities are needed in the arcs
Implies PLC modifications (RE, UA/UJ/US)
102 in the LSS for QRL, SA & IT and MKB (HL-CONS)
without turbo controller
96 in the ARCs for QRL and Magnets (LHC-CONS)
with RadTol turbo controller up to 200 Gy
LS2: end of life replacement of 96 turbos
Turbo controllers relocated in the alcoves
Need to pull long cables

local cables of gauges
Piezo, Pirani, Penning gauges
VRJGE
Example mid-arc left side of IP
Gauges are distributed along the 3km DS/ARC
Group of 3 gauges for IV sectors (Piezo, Pirani, Penning)
Group of 2 gauges for IV pumping groups and BV (Pirani, Penning)
Front-end electronics inside VRJGE convert signals from gauges to analog 0-10V
0-10V sent to the PLC located in a safe service area (Alcove)
Maximum distance between PLC and VRJGE is 1km
PLC converts the analog 0-10V to pressure and provides alarms to CRYO (Piezo, Pirani)

Mini-rack bellow the 1st or 2nd dipole after quadrupole
Mini-rack will house a 3U euro-crate
Each gauge will have a dedicated RadTol card
Modular cards – hot replaceable

10. The 3U euro-crate and the cards
Dedicated front panel for each card – type of gauge
Presently we have up to 7 gauge electronics
Can fit up to 11 front-end cards + the power supply

11. PLC replacement
30 PLC S7-400: used to connect all controllers to SCADA
125 PLC S7-300: used for pumping groups controls
Obsolescence of the CPUs; Insufficient work memory
Replacement of S7-400 PLCs by S7-1500
Replacement of S7-300 CPU by ET200 Profinet
Pumping groups will be controlled by a dedicated master PLC (S7-1500)
Decoupling of master PLCs between beam vacuum and insulation vacuum
